Answer: 1970s

Explanation: The prevailing model for planetary acceleration also known as the fractal assembly dating back to 18th century assumes that the solar system is made up of small grains striking each other chaotically into bigger ones, to form planetesimals.

Plastesimals then collide to form planets. This model was proposed by Russian astronomer Victor Safronov and it was further translated in English in 1970s by George Wetherill.

This remained same for almost next 40 years.
